  1. Directions:(1-5) Study the following graph carefully and answer the given questions
    The Pie chart shows the percentage of population in five different villages. Total population of all the villages are 26800.

    1. Question


    Total population of village A and B is approximately what percentage more/less than the total population of village C?

    Ans: 2
    Population of village A= (26800 * 24)/100 = 6432
    Population of village B= (26800* 16)/100 = 4288
    Population of village C= (26800*28)/100 = 7504
    Total Population of village A and B = 6432 + 4288 = 10720
    Require percentage = [(10720 – 7504)/7504] * 100
    = (3216/7504) * 100 = 42.85% ≈ 43%
  2. 2. Question

    Directions:(1-5) Study the following graph carefully and answer the given questions
    The Pie chart shows the percentage of population in five different villages. Total population of all the villages are 26800.

    If the ratio of the number of male and female in village B is 5:3 then approximately what percentage of male in village B is more/less than the total population of village D?

    Ans: 1
    Population of village B= (26800* 16)/100 = 4288
    Population of village D= (26800* 12)/100 = 3216
    Male in village B = (5/8) * 4288 = 2680
    Require percentage (less) = [(3216 – 2680)/3216] * 100
    = (536/3216) * 100 = 16.67% ≈ 17%
  3. 3. Question

     Ans: 3
    Population of village B= (26800* 16)/100 = 4288
    Population of village E= (26800* 20)/100 = 5360
    Require ratio = 5360: 4288 = 335: 268
